Question

我有一个在Sybase上运行良好的查询，但是在Oracle上运行它时出现以下错误

update table1
        set chk = b.chkakhir
    from table1 a
    inner join (select substr('0'||inkdwil,-2) wil,substr(chk,-4) site, wil||site chkakhir,wil||'0' chkdcust from table2) b
        on a.chk = b.site   
    where length(a.chk) = 4;

update table1
        set chk = b.chkakhir
    from table1 a
    inner join (select right('0'||inkdwil,2) wil,right(chk,4) site, wil||site chkakhir,wil||'0' chkdcust from table2) b
        on a.chk = b.site   
    where len(a.chk) = 4;

在oracle中查询工作

Answer 1

就Oracle而言，语法错误。应该看起来像这样：

UPDATE table1
   SET chk      =
          (SELECT b.chkakhir               --> instead of FROM, you have to use SELECT here
             FROM table1 a
                  INNER JOIN (SELECT SUBSTR ('0' || inkdwil, -2) wil,
                                     SUBSTR (chk, -4) site,
                                     wil || site chkakhir,
                                     wil || '0' chkdcust
                                FROM table2) b
                     ON a.chk = b.site
            WHERE LENGTH (a.chk) = 4);

Answer 2

在oracle中查询工作

更新表1 设置chk =（选择chk 来自表1 a 内部联接（选择substr（'0'|| inkdwil，-2）wil，substr（chk，-4）站点，substr（'0'|| inkdwil，-2）|| substr（chk，-4）chkakhir， substr（'0'|| inkdwil，-2）||'0'chkdcust from table2）b 在a.chk = b.site）上
其中length（a.chk）= 4;

使用内部连接对Oracle错误进行语句更新
